For instance, today the folder inside the archived is named 'gmsh-2.14.1-svn-20161102-source'. Is it an expected behaviour ?

No, Normal{X,Y,Z} is only used to explicitly provide for "1D cracks" (curves)
the normal to the surface in which these cracks live. For 2D cracks the normal
is computed as usual, based on the orientation of the triangles/quadrangles.

Re: [Gmsh] Question about gmsh
If the data is given node-based, this can be done more or less easily with awk. If the data is cell-centered (as it seems to be the case from your description) probably a more complex solution will be needed. Can you give us an example .msh file you want to convert to plain ASCII columns? -- jeremy On Fri, 2016-10-21 at 19:09 -0700, Mayank Jog wrote: > Hello, > > I have been using "simnibs" software which uses gmsh to calculate > electric fields over a 3D mesh/geometry (human head). > > It outputs a final .msh file, that contains the electric field > information, and can be viewed using gmsh. > > > My issue is, I want to convert this file to a list where each line = > [coord location, electric field value ] How do I go about doing it? > > > The ultimate goal is to regrid this data onto a regular cartesian grid > to do some funky postprocessing (fourier transforms, followed by funky > stuff).

[Gmsh] A problem about the format convertion of geometry file in matlab
Dear sir, I have built a 3D geometry model with script and used the extrude keyword. The file is attached. But the meshing result will be different from the result of which I save the file attached as geo file first, and then do meshing. As I am using the matlab to built the geometry model and to do meshing, and I want to use the geo file format, could you tell me that if there is some method to convert the attached file into geo file by matlab? Thank you very much! With best wishes! Yours sincerely, Longlong LI 3D Description: 3D ___ gmsh mailing list gmsh@onelab.info http://onelab.info/mailman/listinfo/gmsh
